My ex and I have broken up about three times, but then he asked me back out on Saturday and I told him that I still had feelings for him, but I didn't want to put myself through that again. Then that Monday I told him that I had thought about it and that I figured that it didn't matter what I said before, and that I loved him. I asked him out and he said he'd think about it. He still hasn't given me an answer, but I found out from his friend that he doesn't want to go out with me. What made him change his mind so fast?
